Neutrophil extracellular trap-associated RNA and LL37 enable self-amplifying inflammation in psoriasis

open access: yesNature Communications, 2020
Antimicrobial peptide LL37 can bind nucleic acids and potentiate their sensing by endosomal TLRs. Here the authors show that LL37 binds to RNA from neutrophil extracellular traps (NETs), which amplifies inflammation and production of more LL37 and NETs ...

Multienzyme (3‐in‐1)‐Mimicking a Single Nucleobase‐Derived Bionanozyme for Versatile Environmental and Biomedical Applications

open access: yesAdvanced Healthcare Materials, EarlyView.
This study reports the development of bioinspired 2D crystalline Bionanozyme derived from a single nucleobase. It effectively mimics multienzyme activity to detect and remove phenolic pollutants, identify disease biomarkers with high sensitivity, and protect cells from oxidative stress.

Targeting of the hepatitis B virus precore protein to the endoplasmic reticulum membrane: after signal peptide cleavage translocation can be aborted and the product released into the cytoplasm. [PDF]

open access: yes, 1988
The major hepatitis B virus (HBV) core protein is a viral structural protein involved in nucleic acid binding. Its coding sequence contains an extension of 29 codons (the "precore" region) at the amino terminus of the protein which is present in a ...

CABS-flex 2.0: a web server for fast simulations of flexibility of protein structures

open access: yes, 2018
Classical simulations of protein flexibility remain computationally expensive, especially for large proteins. A few years ago, we developed a fast method for predicting protein structure fluctuations that uses a single protein model as the input.

Chiral Peptide Nucleic Acids with a Substituent in the N-(2-Aminoethy)glycine Backbone

open access: yesMolecules, 2012
A peptide nucleic acid (PNA) is a synthetic nucleic acid mimic in which the sugar-phosphate backbone is replaced by a peptide backbone. PNAs hybridize to complementary DNA and RNA with higher affinity and superior sequence selectivity compared to DNA ...

Impact of Nanoparticle Stiffness on Endosomal Escape and Signaling Pathways in Cytosolic Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
Nanoparticle (NP) stiffness affects cellular uptake, but its impact on intracellular distribution remains unclear. This study synthesizes silica nanocapsules with varying stiffness, inspired by viral mechanisms, and applies assays to measure cellular uptake and escape efficiency.

Multiscale Profiling of Nanoscale Metal‐Organic Framework Biocompatibility and Immune Interactions

open access: yesAdvanced Healthcare Materials, EarlyView.
A multi‐scale, hierarchical ‘Safety‐by‐Design’ pipeline combining machine learning, ex vivo human blood assays, and in vivo models enables the systematic immunotoxicity and biocompatibility profiling of nanoscale metal‐organic frameworks, accelerating their safe clinical translation. Abstract The clinical translation of metal‐organic frameworks (MOFs) –
